Abstract

A device and method of string a disc-ID on a record carrier. The record carriercomprises tracks. Information is stored on the record carrier. A disc-ID that comprises I groups of disc-ID bits is stored on the record carrier in a scattered way. I comprises at least 1 group. At least one of the I groups of disc-ID bits comprises a plurality of disc-ID bits.

Claims

exact text as granted — not AI-modified
What is claimed is:  
     
       1. A method of storing a disc-ID on a record carrier comprising: 
       providing tracks in which information can be stored; and  
       storing a disc-ID having I groups of disc-ID bits stored on the record carrier in different sectors, wherein I is at least 2, and wherein at least one of said I groups of disc-ID bits comprises a plurality of disc-ID bits.  
     
     
       2. The method of  claim 1 , in which the disc-ID bits associated with one disc-ID are stored in a predetermined number of tracks. 
     
     
       3. The method of  claim 2 , in which a disc-ID byte is formed by eight disc-ID bits having the same position in a direction perpendicular to a read direction of the record carrier. 
     
     
       4. The method of  claim 2 , in which the same number of disc-ID bits are stored in each track of the number of tracks. 
     
     
       5. The method of  claim 1 , in which the disc-ID bits are stored at positions reserved for storing non-data bits. 
     
     
       6. The method of  claim 1 , in which the disc-ID bits are stored in a preamble of the data bits on the record carrier. 
     
     
       7. The method of  claim 1 , in which disc-IDs are stored multiple times on the record carrier. 
     
     
       8. The method of  claim 7 , in which the same number of tracks is used for storing the disc-IDs. 
     
     
       9. A device comprising: 
       means for reading information present on a record carrier  
       means for detecting a disc-ID in the read information, the disc-ID including I groups of disc-ID bits stored on the record carrier in different secorts, wherein I is at least 2, and wherein at least one of said I groups of disc-ID bits comprises a plurality of disc-ID bits.  
     
     
       10. The device of  claim 9 , in which the device further comprises means for providing access to information on the record carrier. 
     
     
       11. A device comprising: 
       means for receiving a disk-ID having I groups of disc-ID bits; and  
       write means to induce a detectable change on a layer of the record carrier for writing said I groups of disc-ID bits on the record carrier in different sectors, wherein I is at least 2, and wherein at least one of said I groups of disc-ID bits comprises a plurality of disc-ID bits.  
     
     
       12. The device of  claim 11 , in which the write means at positions reserved for storing non-data bits. 
     
     
       13. The device of  claim 11 , in which the device further comprises means for providing access to information on the record carrier. 
     
     
       14. A record carrier comprising: 
       a substrate;  
       a disc-ID stored on the substrate of the record carrier the stored disc-ID including I groups of disc-ID bits stored on the record carrier in different sectors, wherein I is at least 2, and wherein at least one of said I groups of disc-ID bits comprises a plurality of disc-ID bits.  
     
     
       15. The record carrier of  claim 14 , in which the disc-ID bits are stored at positions reserved for storing non-data bits. 
     
     
       16. The record carrier of  claim 14 , in which a plurality of disc-IDs is stored on the record carrier. 
     
     
       17. A method of storing a disc-ID on a record carrier comprising: 
       providing tracks in which information can be stored; and  
       storing a disc-ID having I groups of disc-ID bits stored on the record carrier in a scattered way, wherein I is at least 2, and wherein at least two of said I groups of disc-ID bits are stored in different sectors of the record carrier.  
     
     
       18. The method of  claim 17 , wherein said I groups each comprise one disc-ID bit. 
     
     
       19. The method of  claim 17 , wherein said I groups of the disc-ID bits associated with one disc-ID are stored in a predetermined number of tracks. 
     
     
       20. The method of  claim 17 , wherein disc-IDs are stored multiple times on the record carrier. 
     
     
       21. The method of  claim 20 , wherein the same number of tracks is used for storing the disc-IDs. 
     
     
       22. A record carrier comprising: 
       a substrate;  
       a disc-ID stored on the substrate of the record carrier the stored disc-ID comprising I groups of disc-ID bits stored on the record carrier in a scattered way, wherein I is at least 2, and wherein at least two of said I groups of disc-ID bits are stored in different sectors of the record carrier.  
     
     
       23. The record carrier of  claim 22 , wherein said I groups each comprise one disc-ID bit. 
     
     
       24. The record carrier of  claim 22 , wherein said I groups of the disc-ID bits associated with one disc-ID are stored in a predetermined number of tracks. 
     
     
       25. The record carrier of  claim 22 , wherein said disc-ID is stored multiple times on the record carrier. 
     
     
       26. The method of  claim 25 , wherein the same number of tracks is used for storing the disc-IDs.
